Abstract (en)
A method for use in connection with installing an optical fibre into a conduit having a first end and a second end, the method being suitable to detect when the optical fibre introduced into the first end arrives at the second end, and comprising the steps of: - introducing the optical fibre into the conduit from the first end and installing it towards the second end; - introducing light with a light source into the optical fibre at the first end; - detecting reflected light caused by reflection of the light by a surface of the optical fibre, with a light detector at the first end; and - detecting an increase in the reflected light, whereby an operator may determine that the optical fibre has arrived at the second end.
